Moderate southwest wind may build fresh wind slabs in lee terrain features in the alpine.
Moderate southwest wind may redistribute loose snow and build fresh wind slabs in lee terrain features in the alpine on northerly and easterly aspects.
Cornices might grow larger and more fragile.
No recent avalanches have been reported aside from several small loose dry avalanches (sluffs) from steep alpine and treeline terrain.
THURSDAY NIGHT: Mainly cloudy, trace to 3 cm new snow, light to moderate southwest wind, treeline temperature -6 C.
FRIDAY: Mix of sun and clouds with scattered flurries, trace to 3 cm new snow, light to moderate southwest wind, treeline temperature -6 C.
SATURDAY: Mainly cloudy with scattered flurries, trace to 2 cm new snow, light to moderate southwest wind, treeline temperature -9 C.
SUNDAY: Mix of sun and clouds with scattered flurries, trace to 3 cm new snow, moderate southerly wind, treeline temperature -6 C.
5-15 cm of recent snow has buried surface hoar and old surfaces as for example a sun crust on steep solar aspects. Alpine and upper treeline terrain remains heavily wind affected from last week's strong to extreme southwest winds with scouring, sastrugi, isolated pockets of soft snow and layers of hard wind slab. A hard thick crust is found up to 1900 m.
A solid mid-pack sits above deeply buried decomposing crust and facet layers near the bottom of the snowpack (100-150 cm deep). Avalanche activity on these layers has been sporadic and mostly triggered by large loads such as wind slab avalanches and cornice falls. Though unreactive under the current conditions, steep rocky slopes and shallow snowpacks should still be carefully assessed and approached with caution.
